Types of Cloud Computing Services

Cloud computing involves providing
access to a shared pool of computing services. That access is via a proprietary
network or the Internet. Providers deliver these services on a pay-for-use
basis. The term "cloud" refers to data centers all over the world.
These data centers provide the hardware that cloud services need.

The
Three Main Cloud Computing Types

Infrastructure
as a Service (IaaS)

In this model, the provider hosts the
hardware and software. They also host other components of the infrastructure.
The provider maintains the system and handles backups. The IaaS model
is scalable and ideal for temporary workloads. Customers pay per use, which
allows them to avoid the cost of buying their own hardware and software.

Platform
as a Service (PaaS)

With the PaaS model, the
provider offers the hardware and software that customers need to use an
application. This means that the customer does not need to buy the necessary
resources or invest in their upkeep. They will not replace their entire
infrastructure when using the PaaS model; instead, they will use it
for key services. Most PaaS platforms have a focus on software
development. These platforms provide customers with certain advantages. The
advantages include frequent upgrades to features of operating
systems. The PaaS model also helps development teams to collaborate
more effectively.

Software
as a Service (SaaS)

In most cases, SaaS refers to end-user
applications. With this model, the customer no longer has to install or run
applications on their own computers or other devices. This means that they do
not have to cover the cost of licensing software or of maintaining it. Instead,
they pay for a subscription, which replaces the cost of licenses.

Each type of cloud computing can deliver
clear advantages depending on what the customer needs. The most obvious
advantages include scalability, agility, and increased efficiency when
developing prototypes.
